You said:
There is nothing false about teaching Creation. There is nothing false about teaching a young earth- 6 day Creation.
Well, sure there is if a six 24-hour day creation is wrong. Would you not agree with that?
As for the similarity between what I say and what a non-believer says, this is a non-point. If you were discussing photosynthesis and a non-believer was discussing it, you guys would hopefully be saying a LOT of the same things. If I am talking about why evolution is correct, then of course all those who agree that this is true will be saying the same thing, Christian and non-Christian.
Again, the only reason anyone would have a crisis of faith is if they were also hearing that evolution and Scripture were incompatible in some way. Absent that, there is no crisis of faith in the least. Even better, to the extent they hear that they are NOT in conflict, this can ONLY serve to bolster their faith. How could it not?
